The Rigol DSG830 is an RF signal generator operating from 9 kHz to 3.0 GHz, delivering output power from -110 dBm to +13 dBm into 50 Ω. Built for research, development, and production testing, it combines frequency stability of ±1 ppm with phase noise below -110 dBc/Hz at 1 GHz (20 kHz offset) and harmonic distortion under -35 dBc. The instrument supports analog modulation (AM, FM, PM) with internal or external sources, plus configurable digital modulation options. Frequency resolution reaches 1 Hz; output level resolution is 0.1 dB. Sweep capabilities include frequency, amplitude, and phase modes with dwell times from 10 ms to 200 s, enabling flexible test automation. RF output connects via Type N connector (50 Ω). Remote control and instrument integration occur through USB and Ethernet interfaces. Reverse power protection tolerates up to +20 dBm input. The DSG830 operates on 100-240 VAC, 50/60 Hz across a 5°C to 40°C temperature range, making it suitable for bench-top and integrated test systems.
